GOES-U

GOES-19 (designated GOES-U prior to reaching geostationary orbit) is a weather satellite, the fourth and last of the GOES-R series of satellites operated by the National Oceanic and Atmospheric Administration (NOAA). The GOES-R series will extend the availability of the Geostationary Operational Environmental Satellite (GOES) system until 2036. The satellite is built by Lockheed Martin, based on the A2100 platform.

Launch
The satellite was successfully launched into space atop a SpaceX Falcon Heavy rocket on 25 June 2024 at 5:26pm EDT (21:26 GMT), from Kennedy Space Center, Florida, United States. The redesign of the loop heat pipe to prevent an anomaly, as seen in GOES-17, is not expected to delay the launch as it did with GOES-T.

GOES-U also carries a copy of the Naval Research Laboratory's Compact CORonagraph (CCOR) instrument which, along with the CCOR planned for Space Weather Follow On-Lagrange 1 (SWFO-L1), will allow continued monitoring of solar wind after the retirement of the NASA-ESA SOHO satellite in 2025.

GOES-U has a dry mass of 2925 kg and a fueled mass of 5000 kg.
